A CQRPDRATION OF NEW SEWING-IMACHINE GUARD.

Application filed April 11,

Certain types of power sewing machines are equipped with rotary take-up devices on the outer face of'the needle bar housings. The object of this invention. is to provide a guard which will eliminate the danger of the operatcrs hair becoming caught in this takeup device and cause injury as she bends toward the machine to properly see and guide the work. As these machines run at high speed injury from accidental catching of the hair in thetake-up mechanismwould be likely to be of a serious nature.

In order that the guard shall not inconvenience the operator, it is preferable to form it transparent for the most part so that it shall not hinder her view of the. work. It is also so constructed that it may be readily turned out of its guarding position Where it extends between the operators head and the take-up device to a point where she may have ready access to the take-up device when desired.

It is also constructed sothat it may be turned from one to the other of these positions and be maintained in the position desired without special thought or care onthe part of the operator.

For a more complete understanding of this invention reference may be had to the accompanying drawings in which Figure 1 is a front elevation of the sewing machine showing the guard in operative position.

Figure 2 is an end elevation of the same.

Figure 3 is an elevation of the guard and its mounting detached from the machine.

Figure 4 is a detail section on line 41 of Figure 2.

Figure 5 is a detail section on line 5-5 of Figure 4:. i

Figure 6 is a detail section on lines 66 of Figures 2 and 4.

Figure 7 is a fragmentary section on line 77 of Figure 3.

1 indicates the machine frame having an arm 2 terminating in a needle bar housing 3. At the outer face of the needle bar housing is a take-up device comprising a rotating plate 5 having a pivot pin 6 extending therefrom for engagement with the needle thread to effect the take-up action.

The guard attachment comprises a curved plate 10 conforming to the forward edge of the needle bar housing 3 adjacent to its upper' end and having its ends turned up in parallel spaced relation as at 11 to form ears to 1924. Serial No. 705,840.

which may be pivoted mating cars 12 carried by a guard element 13. As shown this guard element preferably comprises a rectangular orother suitably shaped frame 1% holding a piece of transparent sheet material as at 15. in normal operative position this guard 13 extends beyond the face of the needle bar housing in an upwardly and rearwardly in- .cl ined position as shown in Figure 1, thus extending between the operators head and the face of the needle bar housing on which the takenp device is carried. The cars Hand 12 are pivoted as by means of pivot bolts 18 passing through mating perforations therein and the guard may be swung about these pivots into a position extending substantially parallel to the outer face of the needle bar housing and toward the operator so that the face of the needle bar housing may be readily accessible to the operator when occasion therefor should arise, as for example, when it is desired to lead the thread through the takeup to the needle.

In order that the guard may take either of such positions readily at will without esthe guard is in either of its desired positions.

The cars spring apart sufficiently when the guard is forcibly moved out of one of its positions to permit such movmement and to urge the guard into its other position on movement of a su'liieient extent theretoward. It will thus be seen that it is only necessary for the operator when changing the position of the guard to forcibly move it from either of its positions toward the other and when the parts are in proper relation it assumes this other position of itself without requiring-the operator to exercise any special care.

Having'thus described an embodiment of this invention it will be evident to those skilled in the art thatvarious changes and modifications might bemade therein without departing from its spirit or scope as defined by the appended claims.

I claim:

1. The combination with a needle bar housing of a sewing machine having a rotary take-up device on its side face, of a guard plate hinged to the forward edge .of said ing of a sewing machine having mechanism on its face, of a guard plate hinged to the forward edge of said housing adjacent to the upper end thereof and movable between a position projecting laterally from said edge beyond the outer face of said housing and said mechanism and a position extending forwardly from said edge.

The combination with a needle bar hous-, ing of a sewing machine having mechanism on its face, of a guard plate hinged to the forward edge of said housing adjacent to the upper end thereof and movable between a position projecting from said edge beyond the outer face of said housing and said mecha nism and a position extending forwardly nature.

from said edge, and means for resiliently holding said guard plate inone or the other of such positions.

4;. The combination with a needle bar housing of a sewing machine, of a plate fixed to the forward edge of said housing and having a pair of outwardly extending spaced ears, a guard member having a pair of spaced ears each pivoted to one of said plate ears said ears having mating depressions to define resilient stops tending to hold said guard member either projecting beyond the outer fac v said housing or projecting forwardly from said forward edge. 7

5. The combination with a needle bar housing of a sewing machine having a side face with take-up mechanism thereon. of a guard plate hinged to the upper portion of the forward edge of said housing on an axis extending upwardly and rearwardly in a substantially vertical plane and movable to and from a guarding position where it extends out laterally beyond said side face.

In testimony whereof I have aflixed my sig- ROBERT L. LYONS.
